Principally used for variable speed fan interfacing, VPV
Converter TM is a microprocessor controlled
signal converter for residential and commercial HVAC systems. There are two
ways VPV Converter can be connected. The first way, "VP", allows a controller
producing a
variable voltage output to drive an ECM type fan motor
requiring a PWM drive signal. The second way, "PV" allows a controller
producing a PWM ECM output to control a variable voltage driven fan. VPV
Converter detects the type of signal from the controller, and creates the
appropriate output to drive the fan automatically.
| Inputs | Outputs |
|---|---|
| 24 VAC | "G", 0VDC = Off, 12VDC = On |
| 0 - 10 VDC | 12VDC PWM, 125Hz |
| 12VDC PWM | 0 - 10 VDC |
VPV Converter uses analog and digital filters to reject electrical line and system noise. This allows VPV Converter to respond only to the actual input signal and ignore electrical transients caused by motor brushes, contactor arcing, and other noise sources commonly found in HVAC systems.
VPV Converter is compatible with Georgia Controls Atlanta Series controllers, allowing them to drive 0-10VDC variable speed blowers. VPV Converter can also connect to controllers with 0-10V outputs to drive ECM type blower which use 12VDC PWM to control their fan speed.
VPV Converter is housed in a 2 x 4 x 1.5" (5.1 x 10.2 x 3.8cm) ABS box with two mounting tabs. Inside, there are status LEDs and the control board is potted in epoxy to protect it from corrosion and ESD. On top, there are connections for 24VAC, input DC, output DC, ECM drive "G" output, input PWM, and output PWM.
